    Got my OW and AOW this summer, been hitting the water as much as possible and the more I get out there the more I love it.

    I dive a White's drysuit with latex seals and when doing multiple dive per day I get a very irritated neck, soo much so that it can even scab and looks/acts like a burn (resembles a failed hanging). If I'm only out for a single dive I don't notice anything and as far as I'm aware I have no latex allergies, I've had a fair amount of practice with latex *cough**cough**nudge**nudge*

    I'm just wondering if this is a case of the seal being too tight (I'm not choking or anything) or if this is a common problem with latex seals? Should I be going to the expense of having a neoprene neck seal installed or is there something I can do to prevent this? (insert KY joke here)...

    KY wont help - its a water based lube that only helps easy donning/doffing.

    You could try a barrier cream such as dermashield ( Derma Shield - Derma Shield; the ultimate skin protectant™ ) which will help.

    Other than that remember to rinse the INSIDE of your seal as well as out after a day of salt diving as tiny salt crystals form and get abrasive on the inside from the sea and sweat.

    Other than that i find if ive shaved my neck that day it hurts like hell so i dont bother that morning and i get much less of a rash.

    Try a little K-Y Jelly on your neck (no joke)

    Or water soluble silicone spray on the seal

    What he said exactly.

    But scabbing? Wow. I have never seen that. Allergy maybe. Too tight maybe. Salt could do it. The shield should help but shouldn't be needed, even if you shave, to prevent scabbing for crying out loud. Seriously though, scabbing? Ouch. That's not normal. I hope it gets better.:depressed:

    Ive had the scabbing. Its not pleasant.

    fairly common here to keep your suit on for 8-9 hours at a time on a standard diving day. A few days of that sort of abrasion and i get similar issues.

    Edit:- Forgot about these: http://www.apollo-europe.com/bioseals.html

    The neck seal may well stop it. Its a very soft material.

    Drysuit Talc helps me. Yes, it washes off, but it does stay under the seals for a long time--even while under the water. I put "a lot" on my kneck and wrists before I put on the drysuit suit.

    Use SealSaver.

    It's what the manufacturer reccomends to extend the life of the seals (I can confirm it really works in this regard), and I believe it helps prevent the "failed hanging" rash. I usually never have the rash, and my wife isn't so lavish in the use of SealSaver as I am, and it happens to her a lot.


    All the best, James

    I have the same problem. I find that if I shave really well that morning it is greatly reduced. what prevents it almost completely, to where I can get several days of solid diving in with only minimal irritation, is to spray the inside of the seal with a mist of diluted dish soap. I do this on my wrist seals too, its great for helping the seal slide easily into place. plus its much better for cleaning out the P valve than ky :)

    Note: Seal Saver is a water soluble silicone

    Had the same issue for about a year. Went with the Apollo Bio-seal for a stint, but using that I went through seals every 6 months...it was gettign expensive.

    Now, I just powder the seals and apply lots of powder (talc from a billiards shop) directly on my neck and haven't had the scabbing and nasty neck abrasion problem since.

    Thanks for all the replies.

    scubado - I'm only getting the burn/scabbing if I'm doing 3dives+ within 48hrs. As I said before, a single dive and I don't have any irritation or rash at all.

    fdog - I always treat my seals with a healthy dose of sealsaver after rinsing/drying my equipement.

    I will try the talc next time out and see if that helps.
